Okay, after a little investigating, I found the cause, and I've had to
add a special case for an eRuby block with "end" as its first line.
After a couple of other minor tweaks here is the new indenting style
for the above example:

<%
  if true
  %>
  foobar
  <%
  end
%>

I'm not exactly sure what the correct behavior is for this example but
the above was easy to implement and seems reasonable.

I've kept the changes minimal to hopefulyl avoid a broken release.  If
anyone finds any problems let me know.
